Documentation for Program CMPR

Why use CMPR?

CMPR is a multipurpose program for powder diffraction data that provides the following features:

The following sections of this web page describe the various modes within the program. Most sections have links to screen dumps of the GUI with a link marked "View panel" or something similar. The most recent additions are noted with the "new" new image, while other changes that have been added in the previous few versions are flagged with this image: note.

For installation information, see the CMPR/LOGIC overview.

Mouse shortcuts

There are a number of shortcuts implemented by pressing keyboard keys. A list of them follows, either upper or lower case may be used. Some of these case will function only in certain sections of CMPR.

Using the Example File Formats

Supporting Additional File Formats


Grace (xmgrace) is a nice WYSIWYG 2D plotting tool for X Windows. Many UNIX users will be familiar with a prior version of grace, known as xmgr. It is distributed under the terms of the Free Software Foundation public license, and may be downloaded for free. Grace runs on practically any version of Unix. As well, it has been successfully ported to VMS, OS/2 and Win9*/NT. Use in Windows may be somewhat clumsy, as a X-Windows package is required. See the grace homepage at for more information.

I would like to find a Windows program that accepts ASCII input and control files that can be used to generate publication-quality graphics, so that I can generate input files in that format as well.
